在C Sharp中使用Binary Writer编写字符串. [英] String writing using Binary Writer in C Sharp.

问题描述

我已经使用c#中的二进制编写器生成了一个二进制文件，我必须使用VC ++中的CArchive类来读取它.
文件包含长度超过190个字符的字符串.但是当我尝试使用CArchive类读取它时，它在字符串的开头读取了1个额外的空格，因此它跳过了字符串的最后一个字符，这在读取下一个整数值时会引起问题.
(注意:我已经在文件中写入字符串之前应用了Trim())

I have generated a binary file using binary writer in c# which I have to read it using CArchive class in VC++.
File contains the string of length more than 190 characters. But when I try to read it using CArchive class it reads 1 extra white space at the start of the string hence it skips the last character of the string which is causing problem in reading next integer value.
(Note: I have already applied Trim() before writing the string in file)

static void Main(string[] args)
{

  using (FileStream stream = new FileStream("E:\\BinaryFile.dat" , FileMode.Create))
  {
     using (BinaryWriter writer = new BinaryWriter(stream, Encoding.ASCII))
     {
          int user = 99;
          writer.Write(user);
          string versionMain = "Ra-1:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60];";
          versionMain += "Fast And Flurious:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60];";
          versionMain += "Pirates Of Carebian :Ra-1:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60]";
          writer.Write(versionMain.Trim());
          int memDetailsKey = 1234;
          writer.Write(memDetailsKey);
     }
  }
}

在其他vc ++应用程序中，我只是使用CArchive类的对象读取此文件.我能够读取第一个整数值，但是当我尝试读取versionMain字符串时，它读为"Ra-1:8:10 [60]，9:00 [60]，10:01 [60]，11:30 [60 ]，9:10 [60];速度与激情:8:10 [60]，9:00 [60]，10:01 [60]，11:30 [60]，9:10 [60];海盗Carebian:Ra-1:8:10 [60]，9:00 [60]，10:01 [60]，11:30 [60]，9:10 [60.最后一个]"被跳过，这导致读取下一个整数值时出错.

请提出任何解决方案.

In other vc++ application I am just reading this file using object of CArchive class. I am able to read first integer value but when I try to read versionMain string it reads as " Ra-1:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60];Fast And Flurious:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60];Pirates Of Carebian :Ra-1:8:10[60],9:00[60],10:01[60],11:30[60],9:10[60". Last '']'' is getting skipped which is causing error in reading next integer value.

Please suggest any solution.

推荐答案

使用BinaryWriter时，字符串的长度写在实际文本之前.使用整数的可变大小的7位编码来写入长度.尝试通过首先将长度写为32位整数，然后使用Write(char [])重载来写字符来序列化字符串.这样您可以更好地控制.

Espen Harlinn

When you are using BinaryWriter the length of the string is written before the actual text. The length is written using a variable sized 7-bit encoding of the integer. Try serializing the string by first writing the lenght as a 32-bit integer, and then writing the characters using the Write(char[]) overload. This way you have better control.

这很难为我们解决您的问题.您必须在最后调试问题.

首先检查C#应用程序到底要写入什么文件，我的意思是它是否使用空格字符进行写入.

This is very difficult to solve your problem for Us. you have to debug the problem at your end.

first check what exactly C# application writing into the file, i mean it is writing with space character or not.

download this Software[^] to view your binary file.

i think there is no problem in your CArchive (C++) class.
